DRQ-8/100-L48NBZ-C

The DRQ-8/100-L48NBZ-C from Murata Power Solutions is a DRQ-8/100-L48NBxxxx-C series digital control regulated quarter-brick 800W isolated DC to DC converter. It is optimized for distributed power regulated intermediate bus architectures (RIBA), the DRQ-8/100-L48NBxxxx-C series offer regulated outputs in a quarter brick baseplate package. Applications include datacom and telecom installations, cellular dataphone repeaters, base stations, instruments and embedded systems. A wealth of electronic protection features include input undervoltage lockout, overvoltage lockout protection, output current limit, current sharing, short circuit hicc-up, Vout overshoot and overtemperature shutdown. Assembled using ISO-certified automated surface mount techniques, the DRQ series is designed to meet the applicable requirements of UL and IEC 60950-1, CAN/CSA C22.2 No. 60950-1, IEC/EN60950-1, 2nd edition EN55022/CISPR22 conducted emissions and UL94V-0 flammability.
